Back in August, a new game arrived in the iOS App Store and almost immediately vanished without a trace.

“I received a few great reviews from news sites, but not enough to have an impact,” says Robert Topala, founder of RobTop Games and developer of the disappearing game. “Since I had no marketing budget it quickly dropped in rankings after release.”

For most games that would have been it. And if the story stopped there, it wouldn’t have been a tale of total failure: Topala wasn’t a professional coder, and had only been making mobile games for a couple years at the time. Simply finishing a game, getting it in the App Store and picking up a few accolades would have been nice enough.
